化学概念是学好化学的基础性知识,对培养学生的化学能力有着重要作用。化学概念的教学并不是空洞的理论说教,它必须基于一定的探究载体,学生才能在感性的操作中更好地理解概念。教师如何紧扣化学概念的本质属性,有效引领学生理解概念、应用概念?本文从巧妙结合化学实验,有效促使学生掌握概念;巧妙结合具体问题,有效促使学生掌握概念;巧妙结合生活应用,有效促使学生掌握概念三个方面阐述。
Chemical concept is to learn the basic knowledge of chemistry, to develop students’ chemical ability has an important role. The teaching of chemistry concept is not empty theory of preaching, it must be based on a certain carrier of inquiry, students can better understand the concept of perceptual operation. How can teachers closely grasp the essential attributes of chemical concepts and effectively lead students to understand concepts and apply concepts? This article, from the ingenious combination of chemistry experiments, effectively promotes students ’mastery of concepts; cleverly combines specific issues to effectively promote students’ mastery of concepts; cleverly combines life applications to effectively promote Students grasp the concept of three aspects elaborated.
